Advantages of DZL / DZH coal wood fired boiler
DZL model advantages:
More conveninet operation and adjustment.
Clean and automatic boiler fuel feeding device.
Small size appearance, low investment in boiler room.
The boiler is heating up quickly and have high heat efficiency
Automatic and safety running coal/biomass fuel fired boiler.
DZH model advantages:
Manual fuel feeding control.
Low price and low running cost.
Convenient boiler control system.
Strong water quality adaptability.
The output power remain constant.
Superior boiler design features
1. Adopting automatic screw feeding, with reasonable second air
technology and half gasification structure
helping fuel combusting completely, the thermal efficiency can
reach more than 90%. Stable flame, producing steam cautiously.
2. Primordial dust emissions density is low:The volume of the
coal-fired steam boiler is large and there is a dust separation
device, so the primordial dust emissions density will be controlled
much lower than the standard allowed.
3. Control system: Installing microcomputer to operate with
one-button, people just set the process, and it can work
automatically during the operating time. Once any abnormal
situation to happen, stopping automatically with sound-light alarm,
and pointing to the failure code, so it saves time to maintain.
4. Our protected device is safe and reliable. Selecting superior
pressure controller, safety valve, low water alarm, overpressure
alarm, over-temperature alarm, in order to make boilers operate
safely.
5. Heating fast:There are many spiral gas tubes in the boiler and
almost half of the coal fired steam boiler shell can be heated, so
the temperature can up soon.
6. It is simple to clean slag only after burning completing.
